Professor Babu is a theoretical physicist and a Regents Professor in the Department of Physics at Oklahoma State University.. He received his Ph.D in theoretical high energy physics from the University of Hawaii in 1986, under the supervision of Professor Ernest Ma. He held research positions at University of Rochester, Univerity of Maryland, University of Delaware and the IAS, Princeton before joining OSU as an Assistant Professor in 1998. He is an elected fellow of the American Physical Society since 2009. During 2016-2019 he was named a Distinguished Scholar by the Fermi National Accelerator Laboratory, the largest particle accelerator facility in the United States. He was appointed by the American Physical Society as the Vice Chair and the Chair of the selection committee for the J.J. Sakurai Prize in theoretical particle physics, the highest recognition awarded by the APS in this field. He is the recipient of the CAS Outstanding Junior Faculty Award, the Regents Distinguished Research Award, and the Eminent Faculty Award from OSU.
Babu's research interests are in the fundamental constituents of matter and their interactions. His research focuses on the model-building and phenomenological aspects of new physics that goes beyond the standard paradigm which goes by the name "Standard Model". He has proposed novel ideas to unify the different forces and particles in nature under a framework called "Grand Unification". These theories lead to the prediction that matter ultimately is unstable, and he has proposed novel ways of testing these theories in nucleon decay experiments. Babu is a key member of the neutrino theory community, having proposed several testable models of neutrino masses. His 1988 paper on two-loop generation of neutrino masses, known as the Zee–Babu model, provides an alternative to high scale seesaw mechanism. He hasproposed new left-right symmetric theories which can solve the strong CP problem without the need for the axion. He helps organize the annual summer workshop series CETUP* (Center for Theoretical Undersground Physics and Related Areas) in Lead, South Dakota, which is the far-side location of the major Deep Underground Neutrino Detector (DUNE) experiment.

Brief Bio
I obtained my PhD degree in Physics from Cambridge University, UK, attending Trinity College, under the supervision of Nigel Cooper, and Bacehlor of Science and Master of Science degrees in Physics from LMU and TU in Munich, Germany.
Before joining OSU I held postdoctoral positions at JILA (CU Boulder + NIST) working in the group of Ana Maria Rey, and at the Max-Planck-Institute for the Physics of Complex Systems (Dresden) working with the director Roderich Moessner.
Research Interests
My main research interests lie in quantum science, in the areas of atomic-molecular-optical (AMO) and condensed matter theory, focussing on (quantum) many-body physics, quantum simulation, (non-equlibrium) dynamics and generation of entanglement.
On the condensed matter side, I've worked on (classical) spin systems, novel phases that appear in them, and their exotic many-body dynamics, chaos and hydrodynamics. On the quantum side I've worked on a variety of topics, ranging from time-dependent quantum dynamics and Floquet systems, over synthetic dimensions to SU(N) Fermi gases, and quantum spin dynamics of long-range interacting systems, with a particular interest in quantum metrology and spin squeezing.
A main driving motivation of my theoretical work is to provide insightful explanations for experimental results and actionable realistic proposals for the application and exploration of fundamental physics. In my group we enjoy close collaboration with leading experimental groups, ensuring theoretical models are guided by recent novel experimental capabilities. Our research attempts to open up practical new avenues for advancing quantum simulation, quantum information science, and quantum metrology utilizing ultra-cold atomic and molecular setups.

Quick BIo:
Hi! I'm an experimentalist working in the field of condensed matter physics. I'm generally interested in studying emergent phenomena in complex, nanoscale materials and metamaterials with potential applications in future information technologies.
I received my BS in Physics from UCLA, followed by a PhD in Physics at UC Davis working under the supervision of Kai Liu, where I studied high anisotropy magnetic materials. From there, I moved to the Universitat Autònoma de Barcelona (UAB) in Spain to study energy efficient magnetoelectric materials as a postdoc in the Gnm3 group led by Jordi Sort. I follwed this with a second postdoc at Durham University in England as a member of Adekunle Adeyeye's NanoMagnonics group, where I investigated artificial spin ice structures for microwave and magnonic applications. I've been building the Adaptive Magnetic Metamaterials Group at Oklahoma State since Fall 2023.
Research Interests:
I'm generally interested in new, collective behavior in magnetic systems driven by the interplay between chemical complexity, interfacial coupling, geometric complexity. My lab's expertise is focused on advanced nanofabrication and spectrocopy techniques. My current interests include:
- Magnonics: We study magnetic excitations (spin-waves or 'magnons') in engineered metamaterials operating in the GHz-THz range, with potential applications in adaptive computing and 6G communication.
- Magnetoelectrics: We explore how layered heterostructures can offer low-power coupling between an applied electric field and magnetic propoerties. Our lab focuses on ionic conductors and ferroelectric materials couple to magnetic layers in spintronic devices.
- High Entropy Alloys: We explore how chemical complexity in compositional 'cocktails' of 5 or more elements in near equiatomic ratios can offer superior mechinical properties alongside tunable magnetic behavior, ranging from soft to hard magnetic materials. Our work focuses on moving from bulk compositions to tailored nanoscale structures.
- Artificial Spin Ice: We use periodic arrays of ferromagnetic nanomagnets as a sandbox for understanding geometric frustration, order, entropy, and phase transitions. They can also serve as a platfrom for in materia neuromorphic computing,

I'm doing experimental particle physics at the Large Hadron Collider at CERN. I am particularly interested in physics of the Higgs boson and identification of jets from bottom quarks.
Research Interests:
My research interests are in the field of experimental high energy physics. I am involved in Higgs boson physics and identification of jets from bottom quarks at the ATLAS experiment at CERN. ATLAS is one of the two major experiments at the Large Hadron Collider with over 5500 members and almost 3000 scientific authors. The other experiment is called CMS. In July 2012 both experiments have announced the observation of a new particle in the mass region around 125-126 GeV consistent with the Higgs. Six years after its discovery, the Higgs boson has at last been observed decaying to bottom quarks by both ATLAS and CMS experiments.I'm doing experimental particle physics at the Large Hadron Collider at CERN.

Dr. Yingmei Liu is a professor of physics and a Noble Foundation Endowed Chair in laser research at OSU. Her experimental quantum physics research group has generated highly-programmable quantum simulators using ultra-cold quantum gases and investigated their novel applications in quantum information science. Possessing spin degrees of freedom and exhibiting magnetic order and superfluidity, these quantum simulators consisting of ultracold sodium and rubidium Bose-Einstein condensates (BECs) present a remarkable degree of control over many parameters, such as temperature, density, spin, and dimensionality. The main research focus of her sodium BEC lab is to investigate novel non-equilibrium dynamics and develop quantum-enhanced precise magnetic sensors with massively entangled atoms, while her rubidium BEC lab has focused on realizing a topological phase quantum simulator with discrete-time quantum walks in momentum space. These research goals are both of fundamental interest for advancing our understanding on quantum physics and of technological significance.
Liu's quantum physics research group welcomes motivated students and postdocs in physics, photonics, and applied physics. More details of her research group can be found at Liu Quantum Physics Lab
Liu is the director of the NSF-funded QIS-AI Graduate Research Training program and the QIS Graduate Certificate program at OSU. Details of these two graduate programs can be found at aigis | Oklahoma State University and Quantum Information Science (QIS) | Oklahoma State University

I am an experimental condensed matter physicist. I study the chemical, optical and electrical properties of unique materials that we create in my laboratory. This includes silica nanosprings, and more recently, mesoscopic gold polyhedral structures, which we refer to as pyramids. We combine these materials with other materials to create what are referred to as emergent materials - materials that have unique properties that their parts by themselves don't possess.I am a physicist. I like math and stuff like that. I like to play in my lab. I have lots of condensed matter toys that allow me to create unique and interesting materials and study their stoichiometry, morphology, electrical and optical properties.

My laboratory performs research on thin films of complex oxides grown with pulsed laser deposition. We tailor the layering of these materials at the atomic level to create unique electronic environments not realized in any naturally occurring materials. We utilize several in-house characterization techniques to access the quality and basic behavior of these materials. We then perform more advanced measurements at synchrotron x-ray facilities to understand how different atomic layering schemes lead to emergent interfacial behavior at the nanometer scale. The goal of such work is to gain understanding of important phases of matter such as superconductivity, colossal magnetoresistance, and topological phases.
My teaching has focused on Descriptive Physics which focuses on the concepts behind our understanding of the universe, with little mathematical formalism. Beyond this I currently teach an honors physics class on macroscopic quantum phenomena in Bose-Einstein condensates, superfluids, and superconductors. I have previously taught a special topics course on the basics of X-ray diffraction.

I am experimental particle physicist, working on the ATLAS experiment at the Large Hadron Collider. My main interests are searching for new physics beyond the Standard Model, like dark matter particles, precision measurements in the top quark sector, and development of new detector technologies for future high and low energy particle experiments.
Research Interests:
I am interested in searches for new physics in both direct (hints of new particles in data) and indirect ways (deviations from the Standard Model in precision measurements). Our experimental high energy physics group includes three faculty members, two postdoctoral fellows, four engineers, and several graduate and undergraduate students. On the hardware side, we are working on the development of new silicon tracking detectors for future experiments. I am also passionate about applying machine learning methods to the experimental particle physics analyses.I am experimental particle physicist, working on the ATLAS experiment at the Large Hadron Collider.

Our biological physics research focuses on proteins important to health. We use both solution and solid state NMR experimental techniques to study the structure and dynamics of soluble, aggregated, and membrane proteins. Atomic resolution three-dimensional structures of proteins are critical to understand their biological functions and molecular mechanisms of diseases. We also use supercomputer based molecular docking and molecular dynamics (MD) simulation methods to study interactions of potential drug candidates with target proteins, providing important insights on how to redesign molecules for more potent drugs with less side effects.Our biological physics research focuses on proteins important to health.
